Joint bearing classification

Classification of plain spherical bearings: radial spherical plain bearings, angular contact spherical plain bearings, thrust spherical plain bearings, rod end spherical plain bearings.
1. According to the direction of the load or the nominal contact angle, joint bearings are divided into the following types according to different classification methods.
1. Radial spherical bearings—used to bear radial loads, the nominal contact angle ranges from 0 to 45 degrees, and can be divided into:
A. Radial contact radial spherical plain bearings—radial spherical plain bearings with a nominal contact angle of 0 degrees are suitable for bearing radial loads. But it can also take the small axial load while carrying the radial load.
B. Angular contact radial spherical ugly bearings-the the nominal contact angle is higher than 0 degrees, but the radial spherical plain bearings with less than or equal to 45 degrees can bear the combined load of radial load and axial load.
2. Thrust articulated bearing—used to carry axial load, its nominal contact angle is higher than 45 degrees to 90 degrees. According to the difference of the nominal contact angle, it can be divided into:
A. Axial contact thrust joint bearings—Thrust joint bearings with a nominal contact angle of 90 degrees are suitable for bearing pure axial loads.
b. Angular contact thrust joint bearings-thrust joint bearings with a nominal contact angle higher than 45 degrees. Still, less than 90 degrees are suitable for bearing axial loads, but can also withstand combined loads (in this case, the radial load value should not be higher than the axial load 0.5 times).
2. The joint bearing is divided into:
A. Integral outer ring joint bearing;
B. Double half outer ring joint bearing;
C. Single-slot outer ring joint bearing;
D. Double-slit outer ring (split outer ring) articulated bearing.
3. Joint bearings are divided according to whether they are attached to or attached to the rod ends:
A. General joint bearing;
B. Rod ends joint bearings.
4. The joint bearing is divided into:
A. Non-self-lubricating joint bearings;
B. Self-lubricating spherical bearings.
5. Joint bearings are divided into: according to the direction, nominal contact angle, and structure type that they can bear the load:
A. Radial joint bearing;
B. Angular contact joint bearings;
C. Thrust joint bearing;
D. Rod ends joint bearing.
